Section 20 16-Bit Timer Pulse Unit (TPU)
20.4.2
(1)
When one of bits CST[0:3] is set to 1 in TSTR, the TCNT counter for the corresponding channel
starts counting. TCNT can operate as a free-running counter, periodic counter, and so on.
(a)
Figure 20.2 shows an example of the count operation setting procedure.

Select the counter clock
with bits TPSC2 to TPSC0
in TCR. At the same time
select the input clock edge
with bits CKEG1 and
CKEG0 in TCR.
For periodic counter
operation, select the TGRA
to be used as the TCNT
clearing source with bits
CCLR2 to CCLR0 in TCR.
Designate the output compare
register by means of TIOR.
Set the periodic counter cycle
in the TGRA.
Set the external pin function
in pin function controller (PFC).
Set the CST bit in TSTR to 1
to start the counter operation.
